The enzyme maltose-6′-phosphate glucosidase (EC 3.2.1.122) catalyzes the following chemical reaction:

maltose 6′-phosphate + H2O D-glucose + D-glucose 6-phosphate

It belongs to the family of hydrolases, specifically those glycosidases that hydrolyse O- and S-glycosyl compounds. It participates in starch and sucrose metabolism.

Nomenclature

[edit]

The systematic name of this enzyme class is maltose-6′-phosphate 6-phosphoglucohydrolase. This enzyme is also called phospho-α-glucosidase.

Structural studies

[edit]

As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code 1U8X.
